Why is the mRNA not equal in length to the DNA it was transcribed from? 1) the mRNA was longer because it has a Poly A tail 2) T
he mRNA was longer because it contains only introns 3) The DNA was shorter because it does not have the Methylated cap 4) The mRNA was shorter because of Intron splicing
4) The mRNA was shorter because of Intron splicing
Explanation:
In eukaryotic cells, the process of gene transcription uses a fragment of DNA as template in order to synthesize a complementary single-stranded RNA molecule known as primary messenger RNA transcript or 'pre-mRNA', which is then processed to yield a mature messenger RNA (mRNA). This mature mRNA is finally used as template to synthesize a polypeptide chain (i.e., a protein) by the process of translation. RNA splicing refers to the processing mechanism by which a pre-mRNA is transformed into a mature mRNA. During RNA splicing, non-coding regions of the pre-mRNA called 'introns' are removed, whereas the remaining coding regions called 'exons' are joined toghether to form a mature mRNA. In consequence, RNA splicing generates an mRNA that is shorter than the originally transcribed gene sequence.
By definition psychology is studying the human mind while counseling involves aiding in solving ones problems or issues that affect their mental health
An audiometry that assesses the airway and nerve at the same time.
When a person has hearing impairment, will be seen a fall in the audiometric graph both at the level of the bone or neurological pathway above 30 decibels and 250 hertz.
Answer:patient complains of pain, swelling, tenderness on the small joints like hands and feet.. Also early morning joint stiffness that last for long hours..
Explanation: Rheumatoid arthritis is a chronic inflammatory condition of joints.. It affects small joints mostly.. The body system attacks the joints. There is usually a positive history of autoimmune diseases.
